Answer:

A x < 3

Step-by-step explanation:

$\frac{5(9-x)}{3} + 1 < 11$

$\frac{5(9-x)}{3} < 11 - 1$

$\frac{5(9-x)}{3} < 10$

5(9-x) < 10*3

5(9-x) < 30

9-x < 30/5

9-x < 6

-x < 6 - 9

-x < -3

x < 3

Answer:

Height of the student=1.651m

Step-by-step explanation:

Given: Height of a student= 65.0 inch.

To find: Height of a student in meters.

Solution:

We know that 1 inch=2.54 cm, then

65.0 inch will be = $2.54{\times}65.0$

65.0 inch will be= $165.2 cm$

Also, we know that 1cm= $\frac{1}{100} m$ , then

165.2 cm will be equal to= $\frac{1}{100}{\times}165.1$

165.2 cm will be equal to= $1.651 meters$

Therefore, the height of a student in meters will be 1.651 meters.
